mr. secretary. >> good morning, thank you all for being here. special thanks to michael, who you will hear from in just a minute, our outstanding acting faa administrator, had to our very good friend, someone we think so much of, your outstanding mayor, thank you for being here. it is great to be in san francisco, which is no stranger to the power of thinking big and building big. 75 years ago, our forebears' built one of the most iconic symbols of america's vision. the golden gate bridge. it celebrated 75 years strong amidst the struggle of the great depression and in the face of fierce opposition. it would have been too easy to give up and abandon the project, but they did not do that.
